Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different...(View More) frequencies/wavelengths of the electromagnetic spectrum and matter as they investigate the different ways scientists gather and understand remote sensing data, using Dawn instruments as examples. This module is organized around a learning cycle, engaging students through several experiences to activate students' prior knowledge and assess conceptual understanding, informing next steps.(View Less)

In this hands-on activity, learners will build a solar water heater by lining a box with reflective material, adding a translucent cover, and adding water-filled cans that are painted black. The temperature of the water is taken and recorded every...(View More) fifteen minutes. A sunny outdoor location for an extended period of time is required to do this activity.(View Less)

In this hands-on activity, learners will build a solar cooker by lining a box with reflective material and adding a translucent cover. A sunny outdoor location for an extended period of time is required for this activity.

This is an activity about the way distance, albedo, and atmosphere affect the temperature of a planet. Learners will create a planet using a computer game and change features of the planet to increase or decrease the planet's temperature. They will...(View More) then discuss their results in terms of greenhouse strength and the presence of liquid water. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.(View Less)

This is an activity about how much atmospheric pressure is needed on Mars to maintain surface water and why the planet does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring...(View More) the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.(View Less)

This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together...(View More) to make the model. The accompanying information sheet has details about the systems in the satellite including the Dual-frequency Precipitation Radar (DPR), the GPM Microwave Imager (GMI), the High Gain Antenna, avionics and star trackers, propulsion system and solar array, as well as a math connection and additional engineering challenges.(View Less)

In this inquiry activity, teams of students are challenged with engineering a greenhouse heat trap for use with exotic plants. The investigation requires thermometers, plastic wrap, and a shoebox for each team. Students graph data and determine the...(View More) effectiveness of their design. This activity is supported by a textbook chapter, Atmospheric Energy, part of the unit, Energy Flow, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.(View Less)

In this lesson, students explore the cosmic microwave background to understand why it permeates the universe and why it peaks as microwave radiation. Students should be able to explain that the origin of the background radiation is the uniform...(View More) thermal radiation of the big bang and that the radiation produced was evenly distributed around the small early universe, causing it to permeate today's universe. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster.(View Less)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield...(View More) unexpected results, due to unseen events, even though the experiment is precisely planned and executed. The addition of a new technology may clarify factors in the experiment which were previously unknown. Note: the experiment requires advance preparation the day before: two buckets of water are set-up (one with plain tap water, the other with as much salt dissolved in it as possible), which need to be at room temperature. It also requires ice cubes of uniform shape (e.g., from an ice maker or ice trays filled to uniform capacity). This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1993 Cosmic Times Poster.(View Less)

In this lesson, students measure the size of several galaxies to reproduce a plot of Hubble's Law. The goal of this lesson is to give students the chance to simulate the process that led to the notion that the universe is expanding, provide insight...(View More) into how this idea was reached, and inform students about the nature of our universe.Includes an extension activity, "Hubble's Law Mis-calibration." This lesson is part of the Cosmic Times teacher's guide and is intended to be used in conjunction with the 1929 Cosmic Times Poster.(View Less)
